txn2 open source components.

txn2 is an open source organization for components developed by Craig Johnston, sponsored by Deasil Works, Inc. and Plexara. Includes Model Context Protocol servers, command-line tools, and Go libraries covering the modern data stack, Kubernetes networking, and host-file management.

All components are released on GitHub under the MIT or Apache 2.0 license.

§ 01 — model context protocol servers

MCP servers for the data stack

Model Context Protocol servers exposing object storage, distributed SQL engines, and metadata catalogs to MCP-capable clients.

platform

mcp-data-platform

A semantic data platform MCP server that composes multiple data tools with bidirectional cross-injection — tool responses automatically include critical context from other services.

  • composes mcp-s3, mcp-trino, and mcp-datahub behind a single endpoint
  • bidirectional cross-injection: tool responses include context from sibling services
  • persistent memory and insight capture across sessions
  • artifact storage and prompt management

§ 02 — utilities

kubefwd · txeh

FWD-001 · go · kubefwd.com ↗

kubefwd

Bulk port forwarding Kubernetes services for local development.

Walks one or more Kubernetes namespaces, opens a port-forward for every service, and writes hostname entries into /etc/hosts so service names resolve directly on the local machine. Written in Go.

HST-002 · go · txeh.txn2.com ↗

txeh

Go library and CLI utility for /etc/hosts management.

Adds, removes, and lists entries in the system hosts file. Idempotent operations and stable formatting. Used internally by kubefwd and as a standalone utility.
